Look at our conditions. (except as stated in this section) to do the patent license, I recently got about Asano with an unreal engine and he is a professional manga artist. If you are a professional or want to publish a manga, what type of license do you need? It`s curious. This license will be void if any of the above conditions are not met. Nothing in this license is considered to be a right to the trademarks, copyrights, patents, trade secrets or other intellectual property rights of A.M.P.A.S. or contributors, unless expressly stated here. Whether you`re creating a game or developing an internal application for your business, we have a commercial DHD license that meets your needs.

A team creates a game with UDK who wants to sell it. After six months of development, they published the game on digital distribution and earned $60,000 in the first quarter of the calendar after publication.

Your use of the UDK during development does not require a fee. At some point, before the UDK applications are released, they would secure a commercial license under UDK`s license with a $99 licence fee. After earning $60,000, they would have to pay Epic 2,500 $US (0$US for the first turnover of US$50,000 and US$2,500 for the nearest $10,000 in sales). For subsequent revenues, they are required to pay the 25% royalty.

Yes, yes. If the game is absolutely free to play and there is no commercial aspect, then you are welcome to do so as part of the end user licensing agreement.

But some free games still require a license. If your game is free but used to promote a product or service, you will need a license. If your game can be downloaded and played for free, but you sell content, services or products within your game that also require a commercial license. If you are not sure if you need a commercial license or not, please email UDK-licensing@epicgames.com and we will be happy to respond.
